UPLC (Ag+)-CIS-MS selective ion chromatogram of polysulfane mixture 21, with 4 to 15 sulfur atoms: C6H8F2S4-107Ag complex, m/z 352.7, 6.78/6.85 min (split peak due to column issues); C6H8F2S5-107Ag complex, m/z 384.7, 7.71 min; C6H8F2S6-107Ag complex, m/z 416.7, 8.41 min; C6H8F2S7-107Ag complex, m/z 448.7, 9.00 min; C6H8F2S8-107Ag complex, m/z 480.7, 9.50 min; C6H8F2S9-107Ag complex, m/z 512.6, 9.97 min; C6H8F2S10-107Ag complex, m/z 544.5, 10.38 min; C6H8F2S11-107Ag complex, m/z 576.4, 10.7 min; and C6H8F2S12-107Ag complex, m/z 608.4, 11.1 min. With additional signal amplification, the following low abundance complexes could also be seen: C6H8F2S13-107Ag complex, m/z 640.3, 11.43 min; C6H8F2S14-107Ag complex, m/z 672.3, 11.73 min; C6H8F2S15-107Ag complex, m/z 704.2, 12.05 min. The insert shows molecular ions m/z 352.73 and 354.73 corresponding to C6H8F2S4-107Ag and C6H8F2S4-109Ag. The chromatogram selecting for C6H8F2Sn-109Ag complexes was very similar.
